Multivariate Analysis of Aquatic Community Data Using Ordination 2-day workshop presented by the Canadian Rivers Institute
Monday 20 March 2017 - 08:30am - Tuesday 21 March 2017 05:00pm

Course Overview

This two-day workshop will provide an advanced look at the use of eigenanalysis-based multivariate statistics to analyze community and environmental data. Through a combination of lecture material and hands-on training conducting analysis in R, participants will gain an understanding of the use of indirect and direct gradient analysis ordination methods including principal components analysis, correspondence analysis, detrended correspondence analysis, redundancy analysis, and canonical correspondence analysis. Participants will also learn advanced methods to test and compare ordinations, including variance partitioning and Procrustes analysis. Emphasis will be placed on guiding participants through the interpretation of results to give them the tools to move forward with their own analyses.

This workshop assumes that participants have a basic understanding of the use of multivariate analysis, and it is a follow-up to the General Introduction to Multivariate Statistics workshop. Participants should come to this workshop with a basic familiarity with the use of R and RStudio (including how to load and visualize data and how to load packages).

Learning Objectives

At the end of this interactive 2-day workshop, participants will:

  • Understand the mechanics of indirect and direct gradient analysis methods, including PCA, CA, DCA, RDA, and CCA
  • Recognize the difference between unimodal and linear models of gradient analysis, understand differences in interpretation of these models, and know how to select the appropriate model for their data
  • Be able to interpret ordination results and biplots for both unconstrained and constrained data
  • Understand the concept and mechanics of variance partitioning to evaluate the importance of different driving variables
  • Be able to compare ordinations using Procrustes analysis

Action Alerts

ACTION ALERT: Reinstate funding to the Canadian Environmental Network

Friday, 03 February 2017
by Raissa Marks
The Canadian Environmental Network and its provincial affiliate networks need your help!

Historically, the Canadian Environmental Network and its provincial affiliate networks including the NBEN received annual core funding from the Government of Canada. This was used to facilitate networking on environmental issues across the country, coordinate national and provincial issue-based caucuses, coordinate ENGO participation in federal public consultation processes, and maintain open lines of communication between ENGOs and the federal government.

In 2011, as part of the across-the-board cuts to civil society organizations by the previous federal government, all federal funding to the RCEN and its provincial affiliate networks was cut. This left the national network and most of the affiliates with functioning primarily on a voluntary basis with limited capacity to do their work.

There is hope that the current government will provide for renewed funding in its upcoming budget. This funding is crucial for the survival of the national network and many of the provincial affiliate networks. A proposal has been submitted. It now needs strong and immediate support from environmental groups and individuals across the country.

This is where you come in!

Please take a few minutes to write to Prime Minister Trudeau and your MP telling them why you value the RCEN, your provincial affiliate network, or environmental networking at the national level in general. Feel free to use the template letter provided below. You can personalize it based on your experience or simply copy and paste.

Trudeau’s email is justin.trudeau@parl.gc.ca and you can find your MP’s email here: http://www.parl.gc.ca/Parliamentarians/en/members

Let’s show our federal politicians that a strong, well-connected grassroots environmental community is essential to a strong Canada!

Draft Template Letter:

Dear Prime Minister Trudeau,

I am writing to ask that annual core funding to the Canadian Environmental Network (RCEN) be reinstated.

Historically, the RCEN provided a crucial link between environmental groups across the country, both large and small. This link was vital in helping communities address environmental issues right across the country and ensuring a robust approach to the development of environmental policy in Canada.

Since funding was cut in 2011, the RCEN and most of its provincial affiliate networks have been functioning primarily on a voluntary basis with limited capacity to do their work. This is not acceptable. A strong, well-connected grassroots environmental community is essential to a strong Canada. I urge you to reinstate core funding for this crucial work immediately.

Sincerely,
